The end results (some of which you are seeing here) are really cool, but it took a ton of images and trial and error to get these keepers. I took almost a thousand images with my Canon 5D Mark II in burst mode, hoping to get the water droplets in the right moment of action.
In many of the images, I had either no drops of water or nothing of interest in the frame. In others, I had the drops of water but they were out of focus or lit incorrectly.
You will notice that each image has a different color reflection in the water. I was pointing the camera at the bowl of water, but I was trying different pieces of wrapping paper in the background (and pointing the flash at the paper) to get fun reflections off the water.
In the shot above, I actually moved one of my wife's potted plants behind the bowl of water. The green and purple that you are seeing in the water is a reflection of the leaves and flowers. For all of these images, I used the Sigma 150mm macro lens.
Sometimes I would catch one drop of water coming down (from the plastic bag suspended above the bowl) and other times I would catch multiple drops.
It is amazing how beautiful water drops are. I was amazed at the shapes and patterns that I captured with the camera. All frozen at 1/200 sec using the flash to freeze the action.
You will notice that I changed the angle of my camera to get different looks. In the close-up shot (2 above) I was shooting almost directly across the water. In this last image, I was shooting from above, looking down at the water. In this image, the ripples were caused by a preceding drop and then this drop was just about to impact the same spot.
As I look back at all these images, it is hard to believe that I was using clear water. It looks like I used color additives or Adobe Photoshop, but trust me, this was all reflected colors.
